Why is FireFox so slow to initially load web sites, and then works fine?

The last two updates on FireFox, on my Windows 7 64-bit computer, is very, very slow to connect to web sites (20-30 or more minutes.) Once it does, it works fine. It loads quickly from the cache, and it seems to actually connect to some web sites in the first few seconds before the delay begins. The computer has no malware; using Windows firewall; virus software disabled without solving the problem; using Windows Defender. Other computers on the same home network are having no problems with FireFox.

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
Try to decrease the value of the pref network.http.max-connections from 256 to 30 as used in Firefox 3 versions.

Why can't I get my mail, I get a message "connection to server failed" but I can get on all other web sites. It worked fine until about a month ago.

WHY CAN'T I GET MY MAIL, I GET A MESSAGE 'CONNECTION TO SERVER FAILED" BUT I CAN GET ON ALL OTHER WEB SITES. IT WORKED FINE UNTIL ABOUT A MONTH AGO. I CANCELLED MY ACCOUNT, PUT MY INFO IN AGAIN AND STILL GET THE MESSAGE "CONNECTION TO SERVER FAILED" HELP PLEASE!

have you tried removing and readding the e-mail account? sometimes settings get corrupted or changed on the server end...something computers can sometimes handle better than the mail interface.

I can no longer access the itunes store and don't know why.the browser bar at the top loads half way and then stops. Any ideas?I am on windows 7.Thanks.

browser bar at the top loads half way and then stops. Any ideas?I am on windows 7.Thanks.

it seems to work when you reset the port
try this only after you've made sure that any antiviral/firewall software isnt blocking iTunes and the internet connection settings are fine
1. go to windows, accessories and right click on command prompt and run as administrator
2. type in netsh winsock reset (i know sounds ridiculous but it works type WITH SPACES) and press enter
3. Message saying "winsock reset successful now reboot your computer"
4. restart your computer, and open iTunes..backup should run much smoother and faster
5.Click on iTunes store might be working now

Firefox is often "unresponsive";what is 'unresponsive script?why is firefox so SLOW in response to my site requests?

A friend installed Mozilla Firefox for me about 3 months ago to replace Kaspersky which always slowed my computer responses. Now Firefox is slow at responding to looking for my e-mail, at searching for info, and often the message"NOT RESPONDING" following Mozilla Firefox and nothing happens for several minutes. Also, "Unresponsive Script" comes up with the option to cancel or continue--what is "Script" and "WHY"? I have Windows 7 and anE-Machines modem. Also, I am told often that my Anti-Virus is out-of-date even tho' I have it set to update daily at 11:00 pm and I am sure to have the computer ON from 11 to 12 PM each night. How do I fix this? I am a computer 'dummie' and don't understand all the terms and phrases used, but I try. Please help.
Thanks,

Unfortunately Firefox 6 is not as good as it should be.
I recommend you to use latest version of Firefox 3.6.x ,cause it's long release but fire fox 4 , 5 and 6 are short releases and not as good as they should be.

Firefox much slower connecting to all web sites than Internet Explorer. Why?

Over the last few weeks, Firefox has become much slower connecting to virtually all web sites that I frequent than does Internet Explorer. Nothing has changed on my computer other than occasional downloads of Firefox "improvements".

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Or opens a new bower behind the one i'm usind that's blank i don't even know it's there untill i close the one i'm using. How do I prevent Firefox from connecting to google-analytics?

== This happened ==
A few times a week

I got the same issue.
I go on a website and all the sudden another window pops up with "results.google-analytics.com" or "search.google-analytics.com". It has often ads for other sites for example. black single dating site
how can I can I stop that from happening again?

Firefox Sync doesn't sync bookmarks between smartphone and tablet.Works fine between desktop and mobiles.

I have a desktop,smartphone and tablet.They all have the latest FX35.They are all signed in and connected to Sync.Sync is the latest version and it works with email and password, instead of pins.On all devices, Sync is configured to sync all items(bookmarks,tabs etc).
When I enabled Sync on smartphone and tablet, they got my desktop's bookmarks without a problem.They appear in a folder named desktop bookmarks.All the changes reflect properly between smartphone-desktop and tablet-desktop, but, the bookmarks do not sync between smartphone-tablet.
When I open a tab on the smartphone, after a while it appear on tablet's Synced Tabs page.Vice verse is true also.So at least some syncing exists between smartphone-tablet.
Is it possible to create a bookmark on smartphone and have it appear on the tablet and vice verse,just like the synced tabs work ? I tried deleting the sync account and creating a new one, but I still don't see my smartphone's bookmarks on the tablet.
It would be even better if there was an option to choose which device can override another device's bookmarks.I don't really need desktop bookmarks on smartphone, but I'm too scared to delete them.I'm afraid it will also delete them from desktop... ?
Thanks.

HI GeorgePeterson:
So "new" aka "Firefox Accounts based sync" syncs desktop<->tablet and desktop<->phone but not phone<->tablet. Hmmm I actually have tested this S5<->Nexus 5<->desktop (Mac) and it worked.
soooo the big question :-)
# What desktop OS version (e.g. Mac OS X 10.10, 10.8, Windows (Windows 7, 8), Ubutuntu crafty codger ), what tablet and OS version(e.g. Nexus 7 2013, Android 5 Lollipop), what phone (e.g. Samsung Galaxy S5 Android 4.4.2)
I will re-test too!
Cheers!

Firefox will not connect to another web site and it will not reopen after I close it.

I have removed Firefox and reinstalled it. I have tried to disable addons but it still will not open unless I reboot my computer. If this problem cannot be fixed easly, I will have to remove Firefox for good. When it is open, it will not connect to any URL I enter. When I close it it will not reopen and I get a message that says I have to restart Windows. This bug needs to be fixed. It worked one day and the next day it would not work.

I have been using Firefox on this computer for over a year and it worked fine until last week. I get "problem loading this page" anywhere I try to go. I tried uninstalling and re-installing but nothing works.

I can't think of any changes I made that caused it. I have not installed any new programs. My daughter used it for some I-Tunes stuff before it started this problem but I can't say it caused it.

Firefox 6.0.1 will not open .aspx files in a browser window. Safari does it fine. I am greatly disappointed in your lack of help for this problem. Your forum people keep blaming the web site yet Safari works fine.

I tried to read my electric bill and got a message to view in an application or download. I assigned Preview.app to view it and it wouldn't work. Safari opens the bill in Preview.app by default.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).
''(If you're using an added theme, switch to the Default theme.)''
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the '''Restart with Add-ons Disabled...''' menu item: 
[[Image:FirefoxSafeMode|width=520]] 
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
Thank you.

Firefox can't access a specific web site. WHY?

"I have already posted that in 10.4 Forum but the problem is in Leopard"
At home and office I can't access a specific web site with Firefox.
I have tried everything I was able to: cleared cache, deleted cookies, deleted firefox prefs, flushed DNS, tried to log with IP instead of domain, created a new user account in Mac OS, repaired permissions, but nothing happens!
The strange thing is I can access the web site trough a proxy. And I don't have a firewall or similar, my Mac is conected directly to the web. And the problem is the same in any browser I use, like Safari or Firefox or Camino.
Anyone has any idea about what is causing my problem?
Just in case, the site is demonoid.com.
PS: Thanks BDAqua to all support on the other thread.

I feel like a dork. Maybe next time I'll read the post better.
Okay, I went to that site and it works fine for me.

Why is Firefox 4 slowing down my whole Mac? I am not the only one.

My whole Mac Book Pro (five years old running Snow Leopard 10.6.7) has been slowed down. I know someone with a 3 month old Mac Book Pro that is having the same problem. Every aspect of my computer slows down so badly when Firefox is open. I saved a copy of Firefox 3.6.16 just in case thank goodness. I am using it now without a problem. I read you know about this at a Mac Chat Site, and are working on a fix. But I read nothing about it here.

I'm posting another screen shot. This browser is eating up memory like crazy. I have 5 tabs open when this happened. If I try to use another App, it is really slowed down too.

When im logged in on my phone and try to purchase any app, it does the loading spinning circle and then stops. And i can't download anything. Why is this?

Hi ..
Reset the device:
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't help, check restrictions. Settings > General > Restrictions

Firefox continuously brings up errors while trying to load web sites.

Over the past few months I have been having problems with Firefox loading web sites. I get the error of either the connection timed out or server took too long to respond, etc, etc. I have done all the troubleshooting tips like emptying cookies, deleting history and I even started Firefox with all plugins and add on disabled and still the same thing. I did the update for the plugins and all that and still no luck. I even uninstalled Firefox and reinstalled Firefox. I checked to make sure it wasn't my system and I even disabled all addons, plugins, and anti virus software and still no luck. The same thing happens even in private browsing mode. This has been happening ever since the last Firefox update. I can't connect to eBay, Dell, and some others even after putting those sites on the safe lists in my firewall and everything. I have no problems with other browsers. And every once in a while if I click "Retry" the page will load fine. And when the "Retry" button doesn't work, I right click and choose reload which works from time to time. Opening up the error console under "Web Developer" option and select the errors tab, it lists nothing but a bunch of Java exception errors and wrong css coding for the sites.
So what is going on?

Do you have that problem when running in the Firefox SafeMode?
